Abstract
The invention discloses a method for selectively plating a plastic part, which comprises: performing entire plating of an engineering plastic structure to plate a metal layer on the entire engineering plastic structure; etching the metal layer on a part, not needing the metal layer, of the entirely plated product by using a fine etching method according to the precision requirement on the product and removing a part, not needing metal, of the metal layer; and thus, retaining the metal layer of a metal layer part, requiring high precision, of the product and meeting requirements of precision selective plating. The method for selectively plating the plastic part ensures the high precision of a plated area and has a small error. The method can meet the requirements of the precision selective plating of a complex plastic part and improve the qualification rate of the precision plastic part selective plating and the production efficiency.
Description
[technical field]
The present invention relates to the electrolysis or the electrophoresis producing and manufacturing technique technical field of coating, refer to a kind of method of selectively plating plastic part especially.
[background technology]
In electronics/communication product structure product, there are some mechanism elements to need partially conductive, part is non-conductive, is to realize by a series of complex constructions in the past, and adopts engineering plastics parcel plating metal level to realize now.Present engineering plastics parcel plating is all adopted the sealing oil film to hide it earlier and is not electroplated part, then need is electroplated part and electroplates, and takes off the technology that hides rete again and carries out.And this parcel plating method, owing to climb the plating phenomenon when exist electroplating, the precision of plating area is low, error is big, can not realize for the local electroplating pieces of some high-precision requirement.Though or implement but can not satisfy the quality requirements of product.
[summary of the invention]
The object of the present invention is to provide a kind of precision height of plating area, the method for the selectively plating plastic part that error is little.Satisfy the requirement of the accurate parcel plating of complicated plastic structural part, improve the qualification rate and the production efficiency of accurate plastic component parcel plating.
The method of selectively plating plastic part of the present invention, earlier the engineering plastics structural part being carried out integral body electroplates, make it all plate the layer of metal layer, then, by the method for fine etching, whole galvanized products are carried out the metal level that etching does not need the metal level part by accuracy requirement, remove do not need metal metal level partly, thereby make the accurate metal level that requires of this product needed partly keep metal level, reach the requirement of accurate parcel plating.
Selectively plating plastic part method of the present invention concrete steps be:
A), required metal level is electroplated on engineering plastics structural part surface comprehensively with conventional plastic electroplating method;
B) seal all surfaces metal level to the whole plastic structural part spraying corrosion-resistant oil of sensitization electroplated or corrosion resistance coating or with whole electrophoresis method;
C) the plastic structural part surface to spraying or cataphoretic coating needs the part of metal level to carry out the sensitization processing, protects its metal level of electroplating, and makes its surface form the corrosion-resistant oil film of one deck precision; The part that does not need metal level is washed the corrosion-resistant oil film of sensitization or the top coat that laser sculpture is removed does not need metal level is carried out in spraying and this part good coating of electrophoresis; making needs the surface of metal level that coating protection is arranged, and does not need the part of metal level to remove coating.
D) method with fine etching does not need the surface of metal level to carry out etching to product, and the metal level that has plated is etched away, and removes the sealing oil film or the coating of having electroplated the metal level part again, thereby makes product obtain accurate localized metallic layer.
The method of the accurate parcel plating of special plastic structural part of the present invention is that the operation of carrying out the fine etching strip on the galvanized basis of plastic monoblock is carried out, thereby realizes accurate parcel plating.
The invention has the beneficial effects as follows: simplified plastic structural part parcel plating technology, the precision that improves the parcel plating surface makes it reach the accurate requirement that the telecommunications product is special procured, improve the qualification rate and the efficient of complicated plastic structural part, reduce production costs and increase substantially throughput.Can be used for high temperature resistant, corrosion-resistant, the high-strength engineering plastic of resistance to deformation, as PEI, PPS, the accurate parcel plating metal level of the structure product of materials such as PPSA and replace the method for metal parts.Technology of the present invention is simply novel, easy to operate, product precision height.High strength, high temperature resistant, corrosion-resistant, the part of the special plastic structural part of resistance to deformation by parcel plating is in the telecommunications product, because its easy-formation also has metallic character and the effect of local conduction, thereby replaces complicated metallic magnetism structural part, purposes more and more widely.And the present invention has solved the difficult problem of the accurate parcel plating of special plastic structural part on this basis, has enlarged its effective efficiency.Therefore the development to the telecommunications product has important role.
Claims (1)
